Mingw integration

[graham.labdon]

Hello
Please can you help me?
I am using Qt Eclipse integration but cannot get to debug an application
WHen I try I get the following error from the debugger

You can't do that without a process to debug

Does anyone know what this means?

[lyuts]

It means that your mingw installation doesn't have gdb in it. You need to download install gdb for win32 (You didn't mention, so i assume that you are on windows).

I am on windows
I have gdb under the mingw folder in the Qt folder.

If I remove references to Qt objects in my program I can run the debbuger. As soon as I put in the line QCoreApplication a(argc, argv); I can no longer debug

Any other ideas?

Check this tutorial, and make sure you apply step 9.

Hi
THanks for the reply
I am using QT SDK by Nokia v2009.01 which includes mingw
I ahve set uo the environment as in the tutorial but still cannot debug. I cannot now get the program to run either.
Please help, i am tearing my hair out!!

Well, I am using the same version "Qt SDK by Nokia v2009.01" with eclipse and everything is working OK.
how about telling you all the steps that I did from scratch to install Qt+Eclipse?

[graham.labdon]

That would good - thanks

First of all, remove everything you already have (Qt SDK, eclipse, MinGW, any edits to environment Variable(s), etc. )

Now follow these steps:

1. Download and unpack Eclipse IDE for C/C++ Developers to C:\eclipse
2. Download and run the Automated MinGW Installer, and don't forget to select (in addition to MinGW Tools), MinGW Make and the G++ compiler and install in the default path
3. Download and install the GDB, keeping all options default
4. Download and install MSYS again keeping all options default, and when the installation ends, you'll see a prompt (in a command line window) then choose yes twice then enter this string as is: c:/mingw
5. Prepend (Not Append) C:\msys\1.0\bin;C:\mingw\bin; to the PATH Environment Variable
6. Download and install Qt SDK also in the default directory.
7. Download and install Qt Eclipse Integration for C++, all default
8. Append ;C:\Qt\2009.01\qt\bin to the PATH Environment Variable
   Add C:\MinGW\lib;C:\Qt\2009.01\qt\lib to the Lib Environment Variable (if no Lib, please create one)
   Add C:\MinGW\include;C:\Qt\2009.01\qt\include to the Include Environment Variable (if no Include, please create one)
9. Open eclipse and goto: "Preferences -> Qt -> Add", then give these values:
   
   • Version Name: 4.5.0
   • Bin Path: C:\Qt\2009.01\qt\bin
   • Include Path: C:\Qt\2009.01\qt\include
10. Reboot your computer
11. Click the bug icon and select "Debug Configurations", add a new configuration in C/C++ Local Application, notice that C/C++ Application should be "debug/*.exe", not "release/*.exe"! Choose the Debugger tab and set Debugger to gdb/mi. And then choose apply.

And, you're done ( finally )

OK I solved it - you need to set the Qt version in the Qt section of project properties

Thanks for your help

Graham

[Lawand]

I mentioned that you should setup Qt version (step 9)...

Anyway, Good for you.
